Pour spout for facilitating pouring a liquid from a container

Abstract

A pour spout ( 1 ) has an elongate conduit portion ( 3 ) obliquely projecting from a coupling cap portion ( 4 ), which is arranged for coupling to a container ( 2 ). At least one sealing surface ( 6, 7, 8 ) of the coupling cap portion is arranged for sealing engagement around the opening of the container. A venting channel ( 18 ) interrupts the at least one sealing surface ( 6, 7, 8 ) for allowing venting of the container ( 2 ) through a passage between the coupling cap portion ( 4 ) and a portion of the container facing the venting channel. The venting channel ( 18 ) is provided on one single lateral side of the coupling cap portion ( 4 ) only. The lateral side where the venting channel ( 18 ) is provided is in a radial direction in which an angle between the longitudinal direction of the conduit portion ( 3 ) and the plane ( 19 ) is smallest.

1 . A pour spout comprising:
 a coupling cap portion; and   an elongate conduit portion projecting from the coupling cap portion, wherein a pour channel extends in a longitudinal direction through the elongate conduit portion, wherein the coupling cap portion is arranged for coupling to a container with the pour channel in communication with an opening of the container, wherein at least one sealing surface of the coupling cap portion is arranged for sealingly engaging the container around the opening, wherein the coupling cap portion has an internal end surface having an outer circumferential portion extending in a plane, wherein the longitudinal direction of the elongate conduit portion is oriented at an oblique angle relative to the plane,   wherein, in use where the coupling cap portion engages the container, a venting channel space of the coupling cap portion interrupts the at least one sealing surface of the coupling cap portion for allowing venting of the container through a passage formed between the coupling cap portion and a portion of the container facing the venting channel space,   wherein the venting channel space is provided on one single lateral side of the coupling cap portion only, and   wherein the one single lateral side of the coupling cap where the venting channel space is provided is in a radial direction in which an angle between the longitudinal direction of the conduit portion and the plane is smallest.   
     
     
         2 . The pour spout according to  claim 1 , wherein the coupling cap portion has a locally protruding portion on an exterior side that faces away from the venting channel space. 
     
     
         3 . The pour spout according to  claim 1 , wherein the venting channel space includes:
 a first section in a cylindrical, radially inwardly facing surface of the coupling cap portion, and   a second section connecting to said first section extending radially in an end surface extending inwardly from the cylindrical, radially inwardly facing surface.   
     
     
         4 . The pour spout according to  claim 3 , further comprising an annular rib around an end of the pour channel and projecting from the end surface, wherein the venting channel space extends through the annular rib. 
     
     
         5 . The pour spout according to  claim 1 , wherein the venting channel space is provided in the form of a continuous groove in the coupling cap portion. 
     
     
         6 . A kit comprising:
 a container; and   a pour spout comprising:
 a coupling cap portion: and 
 an elongate conduit portion projecting from the coupling cap portion, wherein a pour channel extends in a longitudinal direction through the elongate conduit portion, wherein the coupling cap portion is arranged for coupling to a container with the pour channel in communication with an opening of the container, wherein at least one sealing surface of the coupling cap portion is arranged for sealingly engaging the container around the opening, wherein the coupling cap portion has an internal end surface having an outer circumferential portion extending in a plane, wherein the longitudinal direction of the elongate conduit portion is oriented at an oblique angle relative to the plane, 
 wherein, in use where the coupling cap portion engages the container, a venting channel space of the coupling cap portion interrupts the at least one sealing surface of the coupling cap portion for allowing venting of the container through a passage formed between the coupling cap portion and a portion of the container facing the venting channel space, 
 wherein the venting channel space is provided on one single lateral side of the coupling cap portion only, and 
 wherein the one single lateral side of the coupling cap where the venting channel space is provided is in a radial direction in which an angle between the longitudinal direction of the conduit portion and the plane is smallest; 
   wherein, in use where the coupling cap portion engages the container, the venting channel space extends between the coupling cap portion of the pour spout and a neck flange extending around the opening of the container.   
     
     
         7 . The kit according to  claim 6 , wherein the coupling cap portion has an internal end surface having an outer circumferential portion extending in a plane, and
 wherein the container has a largest dimension in a direction perpendicular to the plane.   
     
     
         8 . The kit according to  claim 6 , wherein the coupling cap portion has a locally protruding portion on an exterior side that faces away from the venting channel space. 
     
     
         9 . The kit according to  claim 6 , wherein the venting channel space includes:
 a first section in a cylindrical, radially inwardly facing surface of the coupling cap portion, and   a second section connecting to said first section extending radially in an end surface extending inwardly from the cylindrical, radially inwardly facing surface.   
     
     
         10 . The kit according to  claim 9 , further comprising an annular rib around an end of the pour channel and projecting from the end surface, wherein the venting channel space extends through the annular rib. 
     
     
         11 . The kit according to  claim 6 , wherein the venting channel space is provided in the form of a continuous groove in the coupling cap portion.
